:CHANnel<n>:UNITs
Syntax :CHANnel<n>:UNITs <units>
Set or query amplitude unit displayed of the specified channel.
Parameter
<n> Discrete {1|2|3|4}
——
{VOLTage|WATT|AMPere|UNKNown}
Return
The query returns VOLT, WATT, AMP or UNKN.
:CHANnel1:UNITs VOLTage /*Set the amplitude unit displayed of CH1 to V*/
:CHANnel<n>:VERNier
Syntax :CHANnel<n>:VERNier <bool>
Description Enable or disable the fine adjustment of the vertical scale of the specified channel, or
query the fine adjustment status of the vertical scale of the specified channel.
Parameter
<n> Discrete {1|2|3|4}
——
<bool> Bool {{0|OFF}|{1|ON}} 0|OFF
Explanation By default, the fine adjustment is off. At this point, you can only set the vertical scale in
1-2-5 step, namely 1mV, 2mV, 5mV, 10mV…10V. When the fine adjustment is on, you can
further adjust the vertical scale within a relatively smaller range to improve vertical
resolution. If the amplitude of the input waveform is a little bit greater than the full scale
under the current scale and the amplitude would be a little bit lower if the next scale is
used, fine adjustment can be used to improve the amplitude of waveform display to view
Return
The query returns 0 or 1.
